Note Submitter: contact at mullanaphy dot com ---- In reply to poutri_j's post (albeit old) about an empty array() == NULL. It's not that an empty array is considered null, its that both are considered FALSE in a comparison. So: <?php $array = array(); if($array==NULL) echo '$array == NULL'; # Echos if($array===NULL) echo '$array === NULL'; # Doesn't echo. ?> This is as expected and something that all newcomers should pick up on. Link to PHP's great reference on comparisons: http://php.net/manual/de/types.comparisons.php
